论文摘要
我们介绍了对混合形状超新星残留HB 9的中心区域的光谱分析的结果。对该来源的先前的牙龈观察检测到了4 keV以上的硬X射线成分，并且该特定X射线成分的起源仍然未知。我们的结果表明，提取的X射线光谱最好由由碰撞电离平衡等离子体组成的模型表示，温度为〜0.1-0.2 KeV（星际问题）和温度〜0.6-0.7 keV和电离时间尺度的电离等离子体的电离等离子体> 1 x 10^ements> 1 x 10^cm}在4 KEV上方的中央区域中未发现明显的X射线发射。以前的工作报告的重组等离子体模型并不能解释我们的光谱。
We present the results of a spectral analysis of the central region of the mixed-morphology supernova remnant HB 9. A prior Ginga observation of this source detected a hard X-ray component above 4 keV and the origin of this particular X-ray component is still unknown. Our results demonstrate that the extracted X-ray spectra are best represented by a model consisting of a collisional ionization equilibrium plasma with a temperature of ~0.1-0.2 keV (interstellar matter component) and an ionizing plasma with a temperature of ~0.6-0.7 keV and an ionization timescale of >1 x 10^{11} cm^{-3} s (ejecta component). No significant X-ray emission was found in the central region above 4 keV. The recombining plasma model reported by a previous work does not explain our spectra.
